LIME-JUICE EXTRACTOR.

Specification of Letters Patent.

Patented Feb. 23, 1215.

Application filed August 17, 1914. Serial No. 857,138.

To all whom it may concern Be it known that I, ROBERT L. WALLACE, acitizen of the United States, residing at San Jose, in the county ofSanta Clara and State of California, have invented certain new anduseful Improvements in Lime-Juice EX- tractors, of which the followingis a specification.

My invention relates to lime juice extractors, and the object of myinvention is to produce a simple, convenient, sanitary, and efiectivedevice for extracting the juice of the lime, particularly whencompounding drinks containing fresh lime juice.

The particular construction and combination of parts used in my deviceare shown in the accompanying drawings, in which Figure 1 is a sideelevation of improved lime juice extractor. Fig. 2 is a bottom plan viewof the same. Fig. 3 is a detail elevation of the plunger. Fig. 4 is across section on line A-A of Fig. 1.

Similar reference numerals refer to similar parts throughout the severalviews.

Referring now more particularly to the drawings, 1 indicates the mainbody portion of my device, made of cast metal or any other suitablematerial, having a neck 2 formed on the upper portion thereof, and anoutwardly projecting flange 3 formed on the upper end of said neck 2.Main body portion 1 is made in the form of a hollow cylinder and isadapted to be placed in a drinking-glass. Radially positioned about theinterior of said body portion 1, and preferably an integral partthereof, are a plurality of blades 4. These blades 4 extend a distanceinwardly and toward ,the center of said main body portion 1, but leave asuflicient space in the center thereof to permit the operation of aplunger as 5. The lower and inner edges of said blades 4 are sharpenedand thereby adapted to cut the half of a lime, as 10, into segments ashereinafter described, said blades 4 extending from the extreme loweredge of said main body portion 1 to a point approximately midway betweensaid lower edge and the juncture of said main body portion 1 and saidneck 2. Neck 2 is also made in the form of a hollow cylinder and isadapted to receive the upper portion or stem of plunger 5. The lowerportion of plunger 5 is of the required size to reciprocate freely inthe central portion of said main body portion 1 between said blades 4,and form a shoulder, as 6, at its point of junction with the upperportion or stem of said plunger 5. The upper end of said plunger 5 isprovided with a threaded pin 7 to receive a push-plate 8. Spring 9 isplaced on the stem of plunger 5 between said neck 2 and said push-plate8 and serves to automatically return said plunger 5 to its positionafter the same has been used as hereinafter described.

In using my device, a lime is cut in halves and one of said halves, as10, is placed fiat side down as shown in Fig. 1. My device is now placedover said lime 10 and pressed downward, causing blades 4 to cut throughthe skin and pulp of said lime and dividing the same into segments asshown in Figs. 1 and 2. The device is now placed in a glass and pressureapplied to plunger 5, whereupon said lime 10 is squeezed downwardagainst the bottom of said glass and the juice forced out into saidglass. When the pressure is removed from said plunger 5, spring 9returns the same to its original position with shoulder 6 against thelower end of neck 2. Blades 4 fulfil a threefold purpose, viz.firstcutting through the skin and pulp of the lime and aiding in freeing thejuice therein; secondly, holding said lime while the same is beingplaced in a glass; thirdly, holding said lime while the same is beingremoved and thrown away.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

A lime juice extractor comprising a hollow cylinder adapted to be placedin a drinking-glass and having a plurality of cutting blades positionedabout the inner circumference of the lower end thereof and extending adistance toward the center thereof and a hollow cylindrical neck formedon the upper end thereof, an outwardly projecting flange formed on theupper edge of said neck, a plunger operatively positioned in saidcylinder and said neck having a shoulder formed thereon adapted toengage the lower end of said neck, said plunger having a push-platesecured to the upper end thereof and a spring disposed on its upper endbetween said push-plate and the upper end of said cylindrical neck,substantially as shown and described.

In testimony whereof I have hereunto affixed my signature 1n presence oftwo sub- 10 scribing witnesses.

ROBERT L. WALLACE.
